The more I read on this site, the more I think I should be shooting a heavier bullet. Right now I have my Omega set up with a Williams Peep, 110 grains of BH209 and 250gr Barnes TMZ. At 150yds, I can still hita milk jugbut when I bench rest it, I expect a better grouping. My patterns are about 4" or so. Would a heavier bullet hold a little better and tighten up my grouping? Lots of folks here shoot a 300gr or heavier. OR, should I just leave well enough alone? I woould like to be able to go ouot to 200yds with confidence. What do yall think?
